高速公路交通事故分布规律及多发位置的鉴别研究

摘要

依据宁连高速公路北段大量交通事故资料，采用统计分析的方法，得出交通事故的时间分布、事故形态分布、事故交通方式分布、气候分布的规律，并分析交通事故在各种状态下的原因。采用适合本路段的累计频率曲线法进行鉴别，寻求最佳曲线进行拟合，得出事故多发位置，并对事故多发的原因进行简要分析。%Through the data accumulation of a great deal of Huaiyin-Lianyungang freeway accidents and with the statistic analysis method, the distribution regularity of traffic accidents, including time distribution, acci- dent form distribution, climate distribution and vehicle distribution is obtained in this paper. Meanwhile, the causes of traffic accidents in different forms are analyzed. The accident accumulation frequency method （AAMF） is presented to identify accident-prone locations, and to search the optimum fitting curve, so as to distinguish the accident-prone locations on the Huaiyin-Lianyungang freeway. Moreover, the main causes of accidents are studied in brief.
